LXDC2HL-G Series

Micro DC-DC converter

1. Features

 Low EMI noise and small footprint (5mm²) using inductor-embedded ferrite substrate

 PFM/PWM automatic mode switching function

 Smooth mode transient between PFM mode and PWM mode with low-ripple-voltage

PFM mode

 2% DC voltage accuracy over full load current range

 Wide input voltage range : 2.3~5.5V

 Fixed output voltage : 0.8V – 2. 5V (factory setting)

 Internal soft start, overcurrent protection

2. Description

The LXDC2HL series is a low power step-down DCDC converter, which is suitable for a space-limited or a noise-

sensitive application. The device utilizes an inductor-embedded ferrite substrate, and the substrate eliminates

radiated EMI noise and conduction noise efficiently.

By just putting input/output capacitors, it can be used as a LDO replacement. Its low noise feature and easy to

assembly feature assures reliable power supply quality.

The device works in PFM mode at light load and it extends the battery life. At heavy load, its control mode

changes to PMW mode automatically and it keeps high efficiency using synchronous rectifying technology. The

device keeps good output voltage accuracy even in PFM mode. It keeps 2% DC voltage accuracy over full

current range, and shows very smooth mode transient between PFM mode and PWM mode.
